A study in the UK has found that alternative sources of protein, such as sprouted wheat and vetch seeds, cereal tails, and processed beans, can replace soy in the pig and poultry sector. The study, conducted over three years, aims to eliminate soy imports and reduce the carbon footprint associated with imported feed. The Center for Organic Research worked with farmers to find ways to produce their own alternative feeds, finding success with vetch and other crops. This could potentially add value to the finished product for organic farmers.
